bmake and other updates necessary for the BIND 9.8.x upgrade.

This includes a structural change regarding atomic ops. Previously they
were enabled on all platforms unless we had knowledge that they did not
work. However both work performed by marius@ on sparc64 and the fact that
the 9.8.x branch is fussier in this area has demonstrated that this is
not a safe approach. So I've modified a patch provided by marius to
enable them for i386, amd64, and ia64 only.

Update BIND to version 9.6.1rc1. This version has better performance and
lots of new features compared to 9.4.x, including:

Full NSEC3 support
Automatic zone re-signing
New update-policy methods tcp-self and 6to4-self
DHCID support.
More detailed statistics counters including those supported in BIND 8.
Faster ACL processing.
Efficient LRU cache-cleaning mechanism.
NSID support.

One more glue update for BIND 9.4.2

Update glue for BIND 9.4.2

Update generated files for BIND 9.4.1

Update bmake glue for the BIND 9.4.1 import.

This includes a return to building with threads, since one of the
major focuses of the 9.4.x branch is to improve thread performance.

Changes to generated files related to the 9.3.3 import.

Reimplementation of world/kernel build options. For details, see:

The src.conf(5) manpage is to follow in a few days.

Updated versions of header files generated per the instructions
in src/contrib/bind9/FREEBSD-Upgrade for the 9.2.3 import

Finish the removal of threads support in ../config.mk,v 1.15.

For variables that are only checked with defined(), don't provide
any fake value.

Fix up the man file installation for the new BIND 9 sources:

1. Install man files and links for the lwres library.

2. Fix the path in various files to say /etc/namedb/ instead of just /etc.

3. Correctly install the conf file man pages for named and rndc.

Ruslan has educated me both on the wisdom of why this approach is
better than mine, and why to wait for review.

Fix the WANT_BIND_LIBS knob by correctly spelling it as WITH_BIND_LIBS
to match how similar syntax is used in the ports system. Thanks to kris
for pointing out my mistake here.

Install the lwres library unless the user defines NO_BIND, or the new
knob, NO_BIND_LIBS_LWRES. There is at least one potential customer
for this library in the wings. Thanks to nectar for the reminder.

Don't expose BIND libraries and their headers to the public by default,
but have a knob (WANT_BIND_LIBS) to build and install them in /usr/lib
and /usr/include. Rumors are that this may be useful at a later point,
let's see.

What this really means is that all BIND libraries are now internal to
buildworld (by default, unless WANT_BIND_LIBS is defined), and linked
statically into various BIND executables.

While here, removed redundant -I's from CFLAGS in lib/bind makefiles.

Clean up and comment config.mk. Centralize more stuff. Bitch if
POSIX threads libraries are not available. Add crypto support if
the crypto libraries are available. Build dnssec-{keygen,signzone}
if crypto is available.
